The unknown songwriter who wrote the Best Song Ever for One Direction stepped in front of the microphone in tonight's Britain's Got Talent in a bid to become a star in his own right.

Ed Drewett, who wrote the number two hit for the boyband as well as The Wanted's chart topper All Time Low, performed another one of his songs for the judges.

The 25-year-old from Essex said: "Ever since I was a kid my dream was always to be a singer. When I was about nine I wrote a song called Frisbee, I sang it to all my friends in the park and from then on I kind of got the bug.

"I would love to be recognised as a singer in my own right that, means a lot to me. It is honestly an incredible experience to hear something you have written yourself on the radio. As incredible as that is my dream was always to be the singer myself."

He missed the chance to impress show boss Simon Cowell who was not at the audition, but left an impression on Amanda Holden who told him the song was "beautiful".

She said: " I am totally gutted that Mr Simon Cowell isn't here because I think he would love you."

Other acts out to impress the judges include drag acts La Voix and the London Gay Big Band who perform New York, New York and 40-year-old Tom whose performance of Somewhere from West Side Story is less convincing.

There are some bum notes towards the end of the show when 54-year-old Eddie Variety, a manager for a postal delivery company, performs the world's smallest disco wearing a toilet costume he built himself.
